How to exlcude the Yootheme Widgetkit component

I had a stab at this, lazyloading does not work with so many of the Widgetkit styles as they create slideshows and effects using background images.

Of course, in an ideal world, I would find a lazy loading plugin that works with BG images, but as that seems impossible, I just need to disable lazy loading for the widgetkit component.

I tried adding com_widgetkit to the component exclusion list in the plugin setup but it did not work.

Any ideas?
